Glengarry Resources has announced that it will shortly commence a 3000m aircore drill program on the Diamantina project 350km south of Mt Isa in SE Queensland.
The drilling will comprise reconnaissance traverses across the MB1, MB2 and MB5 prospects in the Mirrica Bore area where gold geochemical anomalies (up to 30ppb) have been confirmed by recent infill sampling on 500m by 500m centres.
At MB1, a 3km long N/S gold in lag anomaly (up to 13ppb) has been defined coincident with an interpreted fault zone. The southern part of the anomaly is underlain by a discreet magnetic high.
Drilling by BHP during base metal exploration in the mid 1990s intersected Proterozoic basement at 8m depth 5km to the south. Re-sampling by Glengarry of remnant chips around the BHP drill collar recorded up to 0.2g/t gold.
Infill sampling at MB2 recorded many scattered anomalous gold assays (up to 11ppb), however, the strongest and most coherent anomaly, which was defined over a strike length of 2 km, is coincident with a discreet N/S trending linear magnetic low. Previous wide spaced drilling by BHP intersected granite beneath the entire area and the magnetic low is interpreted as an alteration zone associated with mineralisation.
At MB5, anomalous gold in soils (up to 30ppb) has been recorded over 1 by 4km, E/W trending zone. The company says the strongest and most coherent part of the anomaly is coincident with a magnetic high where it is cut by a major WNW trending thrust fault.
Prior to Glengarry commencing exploration in 2003, there had been no prior gold exploration in the Diamantina area (BHP did not assay for gold). The proposed drilling is designed to provide information on depth of cover and bedrock geology and is expected to be followed by a more detailed, closer spaced drill program in 2004 targeting the source of the geochemical anomalies.
